5) Sober sex

6) Endurance

Going back to being well-rested, you'll be like the Energiser bunny hopping around after a full night's sleep - you'll probably last longer too.

7) Can't beat post-sex breakfast

Why not have a fry? You've already burnt off plenty of early-morning calories.

8) You can see each other (debatable)

If it's with your partner, great! You'll get to see them in the flesh and not a darkened room, but if not, depending on the level of drink consumed in Coppers the night before - sometimes it could be better not to see...

9) Laziness

On the flip side to having energy, if it's 6am you can put in as little effort as you want - it's win win!

10) No stress

The morning is no time for stress, so you can enjoy a carefree frolic with a clear head and not have to worry about whatever is on your mind or what happened the night before - if you can't beat the fear then put it off a while.

11) Bragging

What more could you ask for than tormenting colleagues and friends from the minute you smugly stroll in until you tell them for the last time you got laid?
